 DETAILED DESCRIPTION

Referring to FIG. 1, an electrical connector assembly 100 according to a first embodiment is shown. The electrical connector assembly 100 includes a receiving connector 10 and an insert connector 20. In this embodiment, the receiving connector 10 is a kind of female connector, in the form of a receptacle, socket or jack. The insert connector 20 is a kind of male connector, in the form of a plug. The receiving connector 10 is electrically connected with an electronic component (not shown) by four cables 30, and the insert connector 20 is mounted on a circuit board 40 and electrically connected with a drive circuit (not shown) on the circuit board 40. When the receiving connector 10 is connected with the insert connector 20, the electronic component is electrically connected to the drive circuit of the circuit board 40, so that the circuit board 40 can provide an electrical current to the electronic component.

Referring to FIGS. 2 and 3, the receiving connector 10 includes a main body 11 and a locating plate 12 movably attached to the main body 11. The locating plate 12 can be attached at different positions on the main body 11 and slid between the different positions.

The main body 11 includes an insert end 111 and an opposite connecting end 112. The main body 11 defines four receiving holes 113 therein. The four receiving holes 113 are parallel to each other and run through both the insert end 111 and the connecting end 112. The four cables 30 are respectively inserted into the four receiving holes 113 through the connecting end 112. The main body 11 has a side surface 114. A first flange 115 protrudes outwardly from a first lateral side of the side surface 114 near the insert end 111. The first flange 115 is elongated and parallel to an extension direction of each receiving hole 113.

The main body 11 defines a clearance 117 at the insert end 111. The clearance 117 has a low-profile dimension, and is located at a level below the side surface 114. The clearance 117 extends from the insert end 111 towards a middle portion of the main body 11. A tongue plate 118 is formed on the main body 11 above the clearance 117, and at a level generally corresponding to the side surface 114. The clearance 117 is parallel to the side surface 114. A first groove 1141 is defined in the side surface 114 near the first flange 115. The first groove 1141 is elongated and parallel to the first flange 115. The first groove 1141 communicates with the clearance 117, and runs through the insert end 111. A second groove 1142 is defined in the side surface 114 near a second lateral side of the side surface 114. The second groove 1142 communicates with the clearance 117 and is parallel to the first groove 1141, with the tongue plate 118 located between the first groove 1141 and the second groove 1142. The tongue plate 118 has an inner end extending from the main body 11, and a free outer end at the insert end 111 of the main body 11.

A cutout 1143 is defined in the side surface 114 adjacent to the second lateral side of the side surface 114. The cutout 1143 is wider than the second groove 1142 and runs through the insert end 111 of the main body 11. A restricting flange 116 is formed at the second lateral side of the side surface 114. The cutout 1143 is located between a right side of the tongue plate 118 and the restricting flange 116.

An inner surface of the tongue plate 118, which faces the clearance 117, defines two elongated locating notches 1181 therein. The two locating notches 1181 are spaced apart from each other, and parallel to the extension direction of each receiving hole 113. The two locating notches 1181 are located adjacent to the left side and the right side of the tongue plate 118, respectively. Each of the locating notches 1181 defines a triangular cross section. An elongated sliding slot 1182 is defined in the fixed inner end of the tongue plate 118 between the first groove 1141 and the second groove 1142. The sliding slot 1182 is perpendicular to the first flange 1141, and communicates with the clearance 117. A wedge-shaped hook 119 protrudes outwardly from the free outer end of the tongue plate 118. The hook 119 is provided with a hooking step 1191 and a guiding surface 1192. The hooking step 1191 faces the connecting end 112 of the main body 11, and is perpendicular to the tongue plate 118. The guiding surface 1192 extends down at an angle from the top of the hooking step 1191 to the free outer end of the tongue plate 118.

The locating plate 12 is substantially L-shaped. The locating plate 12 includes a sliding plate 121, and a second flange 122 protruding outwardly from a right lateral side of the sliding plate 121. A locating bar 123 protrudes up near a lateral left side of the sliding plate 121. The locating bar 123 is elongated and parallel to the second flange 122. A cross section of the locating bar 123 is the same as that of each locating notch 1181 of the tongue plate 118, i.e., triangular. A sliding bar 124 protrudes up from another side of the sliding plate 121. The sliding bar 124 is elongated, and perpendicular to the second flange 122. A sliding surface 1241 is formed on the sliding bar 124. The sliding surface 1241 is obliquely oriented, and faces towards an outside of the locating plate 12.

When the locating plate 12 is assembled to the main body 11, in one example, the sliding plate 121 of the locating plate 12 is oriented to render the sliding surface 1241 of the sliding bar 124 facing generally towards the insert end 111 of the main body 11. Then the sliding plate 121 is inserted into the clearance 117 of the main body 11 with the locating bar 123 of the locating plate 12 aligned with the right side one of the locating notches 1181 of the tongue plate 118. The second flange 122 is aligned with the cutout 1143. The locating plate 12 is pushed towards the tongue plate 118 and under the clearance 117 of the main body 11. The tongue plate 118 is flexed resiliently by the sliding surface 1241 of the sliding bar 124 until the sliding bar 124 slides into the sliding slot 1182. In this state, the locating bar 123 is received in the right side locating notch 1181; and the second flange 122 of the locating plate 12 is received in the cutout 1143, and abuts the restricting flange 116 (see FIG. 2).

The insert connector 20 includes a rectangular base 21 mounted on the circuit board 40, four pins 22 extending through and out of the base 21, and a fixing plate 23 extending up from a lateral side of the base 21. The base 21 is made of electrically insulating material, while the pins 22 are made of material with good electrical conductivity, such as metal. Bottom ends of the pins 22 are embedded in the base 21 and electrically connected with the drive circuit of the circuit board 40. The four pins 22 are juxtaposed and parallel to each other. The fixing plate 23 is parallel to and faces the pins 22. The fixing plate 23 is provided with a hooking block 231 formed at a top thereof. The hooking block 231 protrudes from the top of the fixing plate 23 towards the pins 22.

The sliding bar 124 of the locating plate 12 can slide in the sliding slot 1182 of the tongue plate 118. When the sliding bar 124 is located at one end of its path of travel, the locating bar 123 of the locating plate 12 is engaged in one of the two locating notches 1181; and when the sliding bar 124 is located at an opposite end of its path of travel, the locating bar 123 of the locating plate 12 is engaged in the other locating notch 1181. In this embodiment, the locating bar 123 is firstly received in the right side locating notch 1181 (the one nearer the restricting flange 116 of the main body 11) to define a gap 128 between the first flange 115 and the second flange 122. A width of the gap 128 is substantially equal to a width of the fixing plate 23.

When the second flange 122 is manipulated by a user so as to slide the locating plate 12 in a transverse direction in the clearance 117 of the main body 11, the sliding bar 124 slides in the sliding slot 1182 of the tongue plate 118, and the locating bar 123 is disengaged from the right side locating notch 1181. The tongue plate 118 is forced by the locating bar 123 to flex resiliently until the locating bar 123 slides into the left side locating notch 1181 (the one nearer the first flange 115 of the main body 11).

During assembly of the receiving connector 10 and the insert connector 20, the insert end 111 of the main body 11 is oriented to face the insert connector 20, with the receiving holes 113 respectively aligned with the pins 22 of the insert connector 20, and the fixing plate 23 aligned with the gap 128 between the first flange 115 of the main body 11 and the second flange 122 of the locating plate 12. The receiving connector 10 is pushed towards the insert connector 20 to cause the pins 22 of the insert connector 20 to respectively insert into the receiving holes 113 of the receiving connector 10. The hooking block 231 of the fixing plate 23 slides along the guiding surface 1192 of the hook 119 of the tongue plate 118 until the hooking block 231 has passed over the hook 119 and hooks on the hooking step 1191 of the hook 119 of the tongue plate 118. Thereby, the receiving connector 10 is mounted on the insert connector 20. Since the gap 128 between the first flange 115 and the second flange 122 is substantially equal to the width of the fixing plate 23, the fixing plate 23 is fittingly sandwiched between the first flange 115 and the second flange 122.

In the present disclosure, the locating plate 12 can be located at different positions in the clearance 117 of the main body 11. Thus, the gap 128 between the first flange 115 of the main body 11 and the second flange 122 of the locating plate 12 is adjustable, which enables the receiving connector 10 to be able to match with different insert connectors 20 with different fixing plates 23 having different widths. Other exemplary embodiments will be described below to help understand the scope and spirit of the present disclosure.

FIGS. 4 and 5 show an electrical connector assembly 100a according to a second embodiment. The electrical connector assembly 100a differs from the electrical connector assembly 100 of the first embodiment only in that the fixing plate 23a of the insert connector 20a faces only three adjacent pins 22 of the insert connector 20a. The insert connector 20a with only the three adjacent pins 22 facing the fixing plate 23a thus differentiates from the insert connector 20 of the first embodiment. That is, the fixing plate 23a has a width smaller than that of the fixing plate 23 of the first embodiment.

Before assembly of the electrical connector assembly 100a, the locating plate 12 is adjusted to cause the locating bar 123 thereof to slide into the left side locating notch 1181 (the one nearer the first flange 115). This makes the gap 128 between the first flange 115 and the second flange 122 substantially equal to a width of the fixing plate 23a. Then, the receiving connector 10 is assembled to the insert connector 20a in substantially the same manner as described above in relation to the first embodiment.

In the above disclosures, the locating plate 12 of the receiving connector 10 is slideable to be located at different positions on the main body 11 of the receiving connector 10, to match with the insert connectors 20, 20a as needed. Thus, the receiving connector 10 can be firmly assembled to the desired insert connector 20 or 20a. Furthermore, when the locating bar 123 is retained in the left side locating notch 1181 (the one nearer the first flange 115), the receiving connector 10 can only be engaged with the insert connector 20a, and cannot be engaged with the insert connector 20. Thus, when the locating bar 123 is in such position, mismatching of the receiving connector 10 with the insert connector 20 is prevented.

FIGS. 6 and 7 show an electrical connector assembly 100b according to a third embodiment. The electrical connector assembly 100b differs from the electrical connector assemblies 100, 100a of the above embodiments only in that the insert connector 20b includes a rectangular base 21b, three pins 22 extending through and out of the base 21b, and a fixing plate 23b extending up from a lateral side of the base 21b. The fixing plate 23b faces the three pins 22. The fixing plate 23b has a width the same as that of the fixing plate 23a of the second embodiment.

Before the electrical connector assembly 100b is assembled, the locating plate 12 is adjusted to position the locating bar 123 in the left side locating notch 1182 (the one nearer the first flange 115) to make the gap 128 between the first flange 115 and the second flange 122 substantially equal to a width of the fixing plate 23b. Then, the receiving connector 10 is assembled to the insert connector 20b in much the same manner as described above in relation to the first embodiment.

Although the number of pins 22 of the insert connector 20b is less than that of the receiving holes 113 of the receiving connector 10, the receiving connector 10 can still be connected with the insert connector 20b by adjusting the position of locating plate 12 of the receiving connector 10. Thereby, the receiving connector 10 has multi-functional adaptabilities.

It is to be understood, however, that even though numerous characteristics and advantages of the exemplary embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and that changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
